3 Claims. (Cl. 229-27) This invention relates to a novel tray forpackaging cakes, cookies and like delicate products and to thepaperboard blank from which the tray is formed. The blank is constructedfrom a single sheet of paperboard without Waste and so formed and scoredthat the blank readily folds into a three compartment tray. Theproduction of a novel blank and tray of this nature comprises a primaryobject of the invention.

The blank embodies a rectangular sheet scored to provide bottom and sidewall panels and two end portions integral respectively with the two sidewall panels. The bottom panel is slotted to receive upwardlytherethrough partition panels carried on the extreme end of the endportions, the end portions thus dividing the tray into threecompartments and supporting the tray in set-up position. The productionof a novel blank and tray of this nature comprises a further object ofthe invention.

These and other features of the invention will be best understood andappreciated from the following description of a preferred embodimentthereof selected for pur poses of illustration and shown in theaccompanying drawing in which- Fig. 1 is a plan view of a blankcomprising the invention, and

:Fig. 2 is a perspective view of the tray formed from the blank.

The blank 10 shown in Fig. 1 preferably embodies a liner sheet 12laminated to a corrugated sheet 14. The blank is of rectangularconfiguration and comprises a body portion 15 disposed between two endportions 16 and is scored along two parallel lines 18 dividing the bodyportion into a bottom panel and two attached side Wall panels 20 andeach end portion into three panels 22.

The bottom panel is slotted transversely thereacross along two spacedlines 24 dividing the bottom panels into three smaller panels 26. Oneend panel 22 of each end portion 16 is integral with one sidewall panel20 along a transverse score line 28 and the other two panels thereof aresevered from the body portion at 30 along the same line. The other endportion is likewise integral with the,

other side wall panel 20 along a like score line and its Patented Nov.22, 1955 The blank (Fig. l) is folded into the tray form (Fig. 2) byfolding the side panels 20 upwardly on the score lines 18. Each endportion 16 is then folded about the score line 28 to form a corner ofthe tray and bring the attached end panel into position providing theend wall of the tray. The outermost end panels 22 are then foldedupwardly about the score line 32 and tucked upwardly through the slots24 and thereupon become partitions separating the tray into threecompartments.

It will now be noted that the two end walls 22 are respectively integralwith the two side walls 26) at diagonally opposite corners of the trayand thus serve to hold the side walls in raised position. Eachintermediate end panel 22 underlies the bottom wall of the adjacentcompartment of the tray and substantially corresponds thereto in shapeand area. The tray is adapted to receive cakes and the like individuallyin the compartments and the filled tray will ordinarily be wrapped incellophane or the like for the market. 1

Having thus disclosed my invention what I claim as new and desire tosecure by Letters Patent is:

l. A paperboard blank comprising a body portion and two end portions andscored along two parallel lines dividing the body portion into a bottompanel and two attached side wall panels and each end portion into threepanels, the bottom panel being slotted transversely thereacross alongtwo spaced lines dividing the bottom panel into three smaller panels,one end panel of one end portion being integral with one side wall panelalong a transverse score line and the other two panels thereof beingsevered from the body portion along the same line, and the other endportion having an end panel integral with the other side wall panelalong a like transverse score line and its other two panels severed fromthe body portion along said like score line, the intermediate panel ofeach end portion corresponding in shape and area to the adjacent smallerbottom panel.

2 A packaging tray constructed from a paperboard blank and comprising abottom wall and two attached side walls, two end walls respectivelyintegral with the two side walls at diagonally opposite corners of thetray, and two vertically disposed end portions respectively integralwith the two end walls and extending upwardly through slots in thebottom wall and dividing the tray into three compartments.

3. The packaging tray defined in claim 2 in which each end wall hasintegral therewith along a score line an intermediate panel underlyingthe bottom wall of the adjacent compartment and integrally connected tothe adjacent vertically disposed end portion along a score line.
